On the Bearing Capacity Parameters of A Single Pile of hammering sunk shaft rammer pile

摘要

This paper studies the bearing capacity parameters of a single pile of hammering sunk shaft rammer pile with engineering practice, proposes three parameters: the shape factor of expanded head α, correction factor of pile tip resistance β and the uplift height h, modifies the calculation formulae of bearing capacity of a single pile and expanded head based on these parameters, and validates the application of these parameters with engineering practice.
